Add a "Label" Interface Tool which can be populated from external source

[Claje]

Hi,

I was just working on an application that targets a back end database, which is currently manually refreshed.  A user on my side requested that we include a "Data Last Refreshed on" text on the application, so that users would see it whenever they ran the app.

I was able to accomplish this by using a Drop Down tool populated using the "External Source" List Values, which is not connected to any Action tool.  However, this is a somewhat ugly solution to the problem - it creates one more clickable object for the user that doesn't actually do anything.

I think having a "Label" tool, which functioned similar to a Text Box (multiline support) but did not allow users to enter values, that included the "External Source" option from the List Box/Drop Down, would be a huge help for Application Development.  This would let you create a configurable message for your users, be it a Last Refresh, runtime instructions, or even a Last Run Date for the application.

This feels like it would be a useful addition for analytical apps, and hopefully not too much effort (since it's similar to a read-only text box)

This would be a nice add
